INFLUENCE OF ILLUMINATION WAVELENGTH ON THE ELECTRICAL PARAMETERS OF A VERTICAL JUNCTION SILICON SOLAR CELL UNDER FREQUENCY MODULATION
Author: Sahin GÔKAN, Ndeye THIAM; Mor NDIAYE, Amadou DIAO, Babacar MBOW and Grégoire SISSOKO
Abstract: The influence of the illumination wavelength on the electrical parameters of a polycrystalline vertical junction silicon solar cell is theoretically analyzed. From the excess minority carrier’s density, the photocurrent density and photovoltage across the junction are determined. By help of both photocurrent and photovoltage, the series and shunt resistance are deduced and the solar cell associated capacitance is calculated.

FACILITATING COMMUNICATION BETWEEN PANTRY UNIT AND BOGIE’s ONBOARD HIGH SPEED LONG ROUTE TRAINS
Author:Abhishek Bondarde1, Rohan Patil1, Mrs. A. B. Kanwade2
Abstract: Railway pantry is inefficient to serve thousands of travelling people. The main aim of the project is to design a system to update presently used pantry system using memory devices and wireless communication. The system which is currently being used involves manually placing of orders which is time consuming and might lead to misplacements. To overcome these drawbacks and to make this process automated one, we have developed a wireless communication system to take the menu from each bogie and directly transmit it to the pantry section. When you want to place an order from bogie just use our system. Keypad is used to take order from the user. When user completes the order, he/she will press the ‘order complete’ key. Order will be sent wirelessly to the counter. At the counter, admin person will send ‘time to serve’ and ‘bill of the food ordered’ back to the user. We are also interfacing thermal printers to print the bill of the food ordered for confirmation purpose. For illiterate people, we have added audio facility. When any key is pressed then audio file corresponding to that key will be played. The conclusion drawn from this work will be used as guidelines for the future implementation of autonomous communication platforms for high-speed rail connectivity.
